RESILIENT STAMP PAD.

Speciication-of` Letters patent. I Patented July 44 1922.

Application :nea` April 11, 1921. serial No. 460,592.

To all whom it may concer/rt:

Be it known that we, ROBERT H. Kun and WHITNEY K. MUNsoN, citizens of the United States, residing at Los Angeles, inthe county of Los Angeles and State of California, have invented new and luseful Improvements in Resilient Stamp Pads, of which the following is a specification.

This invention relates to stamp inking pads, and has for its object the provision of a pad containing an ink reservoir so as to automatically ink the pad` of the device.

It is a further object of the invention to.

provide an ink pad in which the container is formed of resilient material so as not to mar furniture or the like upon which it is placed,

the said resilient container being provided4 with depressions in its under surface adapted to form pneumatic cushioning means. The resilient container is also provided with anannular fiange above the depression hold.

ing the absorbent pad, in order that the resilient fiange' may hold the absorbent pad in position, while permitting of stretching thereof to remove the pad for reversing or replacing the same.y

The invention will be readily understood from the following description of the ac companying drawings, in which:

Figure l is a top plan view of a device vconstructed in accordance vwith the invention, and partly broken away.

Fig. 2 is a transverse section on the line 2 2 of Fig. 1.

Fig. 3 is a plan view of the under surface of the device.

The inking pad includes a container in the form of a base and formed of suitable resilient material, such as rubber. This base, which is shown at 1, is provided at its under surface with depressions, a plurality of which are shown at 2 as a series of circumferentially spaced de ressions forming ribs 2n between the same. y this construction it will be noted that the device may be placed upon a desk or the likewithout dan er of marring the surface of the same,an that the depressions 2 will form air pockets for cushioning the device when struck stamp to be inked. l

The upper surface of the base is provided with a central depression 3 in which is received a suitable absorbent material 4 impregnated with ink so as to form a reservoir. A larger depression 5 extends around and -fiange, and that when the inkin by a above depression 3, and atthe periphery of said depression the resilient base forms an annular resilient fiange 6. An inking pad 7, of suitable absorbent material, is received in depression 5 with its periphery received in the annular groove 8 formed beneath flange 6. It will be noted lthat pad 7 rests upon the` ink impregnated pad 4 so as to be supplied with ink therefrom by capillary attraction. Automatic inking of the pad is thus accomplished.

It will be noted that the provision of resilient retaining flange 6 permits of the ready insertion of pad 74 by stretchin the a has been positioned, the resiliency o ange 6 will positively retain the same in position.

In practicea suitable cover cap 10, which may be formed of metal, is received overA` the top of base l which is preferably formed with an annular shoulder 11 adapted to receive the peripheral liange Vl2 of said top.

It willpthus be seen that an extremely simple butefficient ink-ing pad is formed in which the padis automatically inked, and in which provision is made for retaining the device in position uponv a surface with-A I ility of marring the same,

out the possi while also providing a pneumatic cushion for the structure. Various changes may be made without departing from the spirit of the invention as claime l What is 'claimed is:

1. A device of thevcharacter described' comprising a base, a recess in the upper surface to receive a pad, a second recess in the base of the first recess forming a reservoir, depressions in the bottom of said base, said depressions increasing in depth as radial spacing is increased.

2. A stamp pad comprising a base of resilient material having recesses formed in its under side, an annularliange formed on top of said pad, which fiange is substantially of inverted L-shape in cross section, and an absorbent member arranged within said flange with its edge positioned beneath the horizontal portion of said liange.-

3. A stamp pad comprising a base of resilient material having recesses formed in its under side, an annular ange formed. on top of said pad, which flange is substantially of inverted L-shape in' cross section, an absorbent member arranged within said flange with its edge ositioned beneath the horizonthe center of said base, the top of said base 10 tal portion o said fiange, there .being a debeing provided with a depression, and a pression formed lin the central portion of the body of absorbent material'within said detop of said resilient base, and an absorbent pression. member positioned within saiddepression'. In testimony whereof we have signed our 4. A stamp pad comprising a base of renames to this specification. y silient material provided in its under side with a plurality of arcuate depressions that A ROBERT H. KEE.

are concentrically arranged with respect to WHITNEY K. MUNSON.
